VALVE AND OPERATING MECHANISM THEREFOR.

Application filed April 15, 1925.

This invention relates to improvements in drain cocks and means for operating the same.

The primary object of this invention is the provision of an improved valve mecha nism or drain cock adapted to be used in connection with the water cooling systems of internal combustion engines, to facilitate the drain of water from the cooling system.

In connect-ion with conventional cooling systems for internal combustion engines, the drain cock is generally inaccessibly located, so thatit is an extremely tedious operation to open and close the same, resulting in much loss of time and soiling of garments. It is known that the water should be drained from the cooling system frequently, and in winter time when it is not desired to use anti-freeze solutions, the water should be drained during periods when the internal combustion engine is not in use. To permit the facile draining of the water from the cooling system, theimproved valve mechanism and operating means therefor has been provided, which may be easily operated by a pedal from the drivers compartment or other similar easily reached location.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specificiation, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevation of the improved valve mechanism and operating means therefor as applied to the internal combustion engine of an automotive vehicle.

Figure 2 is a side elevation of the operating details of the invention, showing the same in position for holding the valve open to drain water from the cooling system.

Figure 3 is an enlarged sectional view taken through the valve details of the invention.

Figure 4c is a plan view of an operating pedal support of the invention adapted to be located upon some convenient place on the automobile, such as 011 the floor boards in the drivers compartment.

Figure 5 is a plan view of an improved operating lever mounting, showing the same in retained position to normally hold the valve open.

Figure 6 is a sectional view taken on the line 6-6 of Figure 5, and showing more Serial No. 23,370.

particularly the retaining means for holding the operating lever in position to maintain the valve open.

In the drawing, wherein for the purpose of illustration is shown only a preferred em bodiment of this invention, the letter A may generally designate an internal combustion engine, which may be of the water cooled type, and with which the water cooling radiator B may be associated, and connected to the water jacket of the engine A as by a lower conduit C and the conventional upper conduit D. If desired the water cooling system may be of the pump operated type, utilizing a pump E for pumping the water from the radiator thruthe conduit C to the water jacket of the engine A. The improved valve mechanism and operating structure may be generally designated letter K, and comprises the valve structure or drain cock M and the operating means P therefor.

Referring to the structure of the valve M, the same includes a casing 10, of substantially oval-shaped construction, preferably comprising detachable upper and lower parts 11 and 12 respectively, and providing the enlarged valve compartment 13 therein. The upper and lower sections may be detachably connected in any approved manner to facilitate the assemblage of the valve member 1a in the compartment 13. The casing at its upper end is provided with a reduced screw threaded shank 16. having a reduced passageway 17 therethrough, and this reduced shank 16 is adapted for detachable connection in a nipple 20 formed at the lowermost part of the water conduit C, so that the water from both the water jacket of the engine A and the radiator B may drain in its entirety into the valve casing compartment 13. The valve casing 10 at its lower end, and diai'netrically opposed and axially related to the screw threaded shank 16 provides the valve supporting extension through which the valve member 141 reciprocably extends, in any approved manner, and preferably in a bushing 26, although such need not be provided, but is preferable. This valve member 14 includes the disc-shaped substantially concavo-convex head 28 adapted to seat upon the tapered seat'29 provided at the bottom of the compartment 13, and furthermore includes the straight shank which extends through the passageway of the nipple 25 and the bushing 26, and at its lower end extends below the casing 10. The" housing 10 is provided with a downwardly inclined drain duct 32, justbelow the valve seat 29., which is adapted to be closed oil from the compartment 13, when the valve 28 is seated, and as is illustrated in Figure 3 of the drawings.

The radial supporting extension 35 is preferably P ovided. at the ve an if h nipple 25, having a link 36 pivotally con nected therewith; a connecting lever 87 ben pivetaily conne ted at t e pp @1151 ot'fsaid li 'iln The valve stem 30 at its lower xt rior e d is pi' ot y conn t d at O with the lever 37, between the ends of the la t r, and a lv spr ng 41 s d p s axially aboutthe stem 80, under compression between the lever 37 and the nipple 25, to no mally f rce he valv head p n its salt, amiss ca readily be un erst from Figure Slot the drawing.

Re e ring tothf opera i g mean y means of which "to lift the lever 87 and lif he valve 1. o its sea th s m p eferab y c mp ises a bell ank level 50, pivot-ally mounted at 51 in any approved relation upon a support of the engine A; or chassis of the vehicle with which the engine is associated. At one end of the bell crank lever 50. a connecting rod 52 is pivotally associatd extendn i, ward he e e an b ing o 'e d w th he le er 37 at a. point on the n h eof Opposit t the i k ns ed end, by m s of a ten on piral spr ng 5,. wh ch. s .61' 1a y n r tens o a pu l t eh l ank lever; nto the pos ion llust ated i 11 Figure At i s th r end. h l C ank ever 50; piv ta y co ne te to ada able 5. nd at it oppos e n the cenn et n's ro 57 i p v al y Co nect-e at 58 to a pedal or operatinglever 59 pivotal y moun ed p n aispecia i supp 6 provided therefor.

The pedal operating lever and support therefor are preferablyconstructed of sheet metal, and the support 60 generally coni- Pr s'es' a ec ang ar sh ped body p o 6 which may be attached as by screws 62 upon the floor board '65,? of; theveliicle. Adjacent its'forward end the support body 61 is prod it th upward y xt nd g p ral e s 3 PiYOta lY animating th l v r 59 eretqi as by bolt 6-.

From the foregoing description of this invention the operation of the improved valve will be apparent. Merely by pressing upon the pedal at its free end the connecting rod 57 will be pulled to rock the bell crank lever 50, and through the intermediary of the connecting rod 52, the spring 55, and lever 37, will elevate the valve 14L to lift head 28 oil its seat and cr'mit water to drain from the cooling system through the compartment 13 and out of the duct 32.

Various changes in the shape, size, and arrangement of'parts may be made to the form of invention herein shown and de scribed, without departing from the spirit oii'the invention or the scope of the claims.

I claim:
